Under the conditions that the incidence angle, incidence position and the intensity of the pump wave ensure a stable phase-conjugate wave output, the effect of the pump wave intensity change on the stability of the phase- conjugate wave is investigated. The experimental result shows that for some pump wave intensity, when the phase-con jugate intensity reaches its saturation value, the change of pump wave intensity may induce an instable phase-conjugate output.
